  • Patent number: 9138734
    Abstract: Object of the present invention is to provide visible light-responsive photocatalyst coating material which can form a coating film exhibiting superior allergen inactivation property through irradiation of visible light. The visible light-responsive photocatalyst coating material comprises: photocatalyst material having visible light-activity composed of metal oxide particle with divalent copper salt supported on the surface thereof, said metal oxide particle having optical semiconductor-characteristics and potential of valence band of said metal oxide particle being 3[V] or more (vs. SHE, pH=0); binder component including component having siloxane bond or component forming siloxane bond through reaction; and chloride ionic compound. When visible light is irradiated to the coating film, the metal oxide particle exhibits photocatalyst activity in the presence of the copper-divalent ion and chloride ion, thereby significantly high allergen inactivation property is exhibited.
